A local 2nd hand Swiss watch dealer/shop runs their online store off a Wordpress set up (no e-commerce/online payments though). Sometimes when I visited to look at their current stock, when clicking into something of interest I would get bombarded with all sorts of random adware crap, new tabs etc. opening with blogspam - typical “Win an iPad” type stuff. The owner was totally unaware, as this never happens to them - they are logged into the site the whole time, so it deliberately never triggers/fires itself as they make updates, etc. It was also somewhat random for users of the site, but when users see it, they probably just close it / ignore it. Nobody told them this happened when browsing their website so they were totally unaware they had been comprised. Moral of the story, always occasionally browse your own web properties from other devices and incognito windows, etc. to see what other people see.
